Car loses voltage when idealing

I replaced my alternator and battery but the battery still isn’t charging.

I thought Maybe i need to replace a blow fuse but I don’t know which fuse to replace. I looked online but it isn’t clear on which fuse I should replace for alternator. Please HELP!!!

Battery goes dead after a few days of not starting it. Pulled every fuse and unplugged the alternator. Still dies. Meter did not drop on any fuse.

Electricity fully operational, no sounds at all from turning the key. If I let the car sit for 2 hours, it'll fire right back up. New starter, battery, and alternator already replaced. What should I do? I think the problem in in the fuse box but idk where to start.

Replaced battery and alternator and still need to jump battery to start, and all electrical acting like it's having a seizure
